//...
comptr<IVectorView<IShellItem2>> spItems;
hr = pFolder->GetItems(&spItems);
//...
comptr<IIterator<IShellItem2>> spIter;
hr = spItems->First(&spIter);
//...
bool hasCurrent;
for (hr = spIter->get_HasCurrent(&hasCurrent); 
     SUCCEEDED(hr) && hasCurrent; 
     hr = spIter->MoveNext(&hasCurrent))
{
    comptr<IShellItem2> spAnItem;
    hr = spIter->get_Current(&spAnItem)
    //...
}
